FFmpeg/libavfilter/vaapi_vpp.c
Nicolas George 2f76476549 lavfi: regroup formats lists in a single structure. 
It will allow to refernce it as a whole without clunky macros.

Most of the changes have been automatically made with sed:

sed -i '
  s/-> *in_formats/->incfg.formats/g;
  s/-> *out_formats/->outcfg.formats/g;
  s/-> *in_channel_layouts/->incfg.channel_layouts/g;
  s/-> *out_channel_layouts/->outcfg.channel_layouts/g;
  s/-> *in_samplerates/->incfg.samplerates/g;
  s/-> *out_samplerates/->outcfg.samplerates/g;
